An integrated dynamic model of road traffic congestion based on simple car-following theory: exploring hypercongestion

Article Abstract:

A study is presented that explains that hypercongestion only occurs when cars are filling up access points, creating bottlenecks in the traffic flow.

Inside the queue: hypercongestion and road pricing in a continuous time-continuous place model of traffic congestion

Article Abstract:

A continuous-time-continuous-place dynamic economic model of traffic congestion on the basis of a car-following theory is presented. This model provides the simplest plausible dynamic extension of the standard static economic model of traffic congestion.

Congestion caused by speed differences

Article Abstract:

A study was performed to examine the effect of differences in driving speed on road traffic congestion. This research generated analytical expressions for optimal tolls, investigate second-best tolling and explore the concept of 'platooning,' which is a recommended policy where slow drivers are required to wait at the road entrance until a large enough number of them have accumulated, at which point they are permitted to begin their trips en masse like a platoon. Findings revealed that optimal tolls for slow vehicles are higher than those for fast drivers. Moreover, the marginal external costs and the optimal tolls for slow drivers was found to be going down in the equilibrium number of slow drivers. Finally, platooning may be desirable, particularly if the desire for a low speed is the result of a lower value of time.
